摘要： This sliding bearing comprises a pair of semicircular half bearings formed into a cylindrical shape by bringing both circumferential ends thereof into contact with each other. The axial width of the half bearings is narrower in both circumferential ends and the circumferential center, and wider in the quarter parts located therebetween. During manufacturing of the half bearings, finishing by cutting processing is first performed on the parts of a flat-plate material which after formation are to become the two axial-direction end faces and the two circumferential-direction end faces of the half bearings, and thereafter, the flat-plate material is deformed into a semicircle.

摘要： The properties of a lubricating oil are utilized to avoid excessive quality in terms of the circularity of roller members while reducing the noise from a radial roller bearing alone during rotation and thereby reducing the noise from a rotary machine. A radial roller bearing includes an outer ring member (30A), a plurality of roller members (30B), and a retainer, and a lubricating oil (0) is supplied between the outer ring member (30A) or a rotating shaft and the roller members (30B). The circularity (ΔR) of the roller members (30B) in a cross section perpendicular to a centerline (CL) thereof is set to be lower than or equal to the minimum oil film thickness (hmin) of an oil film formed by the lubricating oil (O).

摘要： A wheel bearing apparatus has a protecting cover formed from non-magnetic steel sheet with a cup-shaped configuration. The protective cover has a cylindrical fitting portion, a disk-shaped shield portion, a radially reducing portion, a stepped portion and a bottom portion. The cylindrical fitting portion is press-fit into the inner circumference of the inner-side end of the outer member. The disk-shaped shielding portion extends radially inward from the fitting portion, via the radially reducing portion. The inner-side surface of the shielding portion is arranged close to or in contact with a rotation speed detecting sensor. The bottom portion is continuous with the shielding portion, via the stepped portion to close the inner-side end of the inner member. A full deflection of the side surface of the shielding portion that is caused by a load the same as that applied to the protecting cover when it is press-fit into the outer member is limited to a predetermined value or less.
